A comparison of instantaneous and fryze power calculations on P-F and Q-V droop in microgrids

Power frequency droop is the generally accepted method to control power flow in a standalone microgrid. This paper compares the effect of instantaneous and Fryze power calculations on the operation of a three phase, two inverter microgrid. Similar control schemes are implemented based on each power calculation method and the behavior of the microgrid analysed. SABER® simulations compare the two control schemes and the results are utilised to outline the respective benefits of each method.
